Application :Filed .august 2 l To all fui/zow?, t 'may concern.

Be it ltnowu that l, .losser-r F. LYNCH, a citizen, ol the Unitedvltiues, residing` at Stoel-Iton, county of San Joaquin, .State ofCalifornia, have invented certain new and useful lmproreinents inDirection Signals :for Automobiles: and .l do declare the to? lowiirgvto be a tull, clear, and exact de scripi'iion of the same, referencebeing had to the acccom Danying drawings, and to the characters oilreference marked thereon, which iiorm a part oit this application. Thisinrei .elates to improvements dii'eetion-givingv signal device torautomobiles= ot a kind which maj.' be readily seen either by niojht orday, and from both ends and sides or the 'Vehicle lic. present inventionis particularly an improvement over the signal shown in my Patent lo.1,357,0tl-a-, date Torf-rubor 2nd, i920. my main object now ugr tosimpl' the construction and installation et the device rou'i what isshown in said patent,

without (letractingl from the ciliciency ot operation `Visibility ot thesignal.

A ii'urthcr object of thc inreution is to produce a simpe andinexpensive device and yet one which will be exceedingly effective forthe purposes :tor which it is de i red.

These objects l acccomplish by inea-ns oft such structure and relativearrangement ot parts will. lully appear by aV perusal ot the 'folowina'specihcetion and claims.

.ln the drawings similar characters ot" reference indicatecarrespfmdiuaF parts in the several views:

Fie'. t is a perspective outline of an automobile fshowinplg' improvedsignal installed thereon,

Fig. 2 is an enlarged side View ot one ot rial members.

is a rear end View of the same. l is a plan View ot the signal-moyementcontrol means.

Fig. 5 is a detached end View of a` contact member.

Referring' now more particularly to the characters ot reference on thedrawings, the numeral 1 denotes a pair of bracket or trame strtuztures7adapted to be fixed onto bot-h rear or front wheel :tenders 2 of anautomobile, preferably at the higjholt point thereon.

Pivoted in the brackets on shafts extending longitudinally of' theVehicle are the 1922. Serial No. 584,641.

Spri dj Contact strips 10, insulated `ach other and mounted .inconnection liracket structure 1, are adapted to he contacts 8simultaneously only the disc. 9 is in certain positions. A lead 11 tromstrip 10 connected with the lead to the tail lamp 12 ot the Vehicle,while the lead 'from` the other strip 10 is grounded at a suitablepointA Bj.' means this construction, the lights will never be lit unlessthe tail light 12 is si, which ot course is only at night. Further, thecontacts 8 are so located on the discs 9 with respect to the axial linesot the signal arrows that the strips will only engage therewith, so toclose the circuit to the lamps, when said arrows are pointing; ahorizontal direction either to the right or left.

ltlorement is imparted to both signal members simultaneously, and sothat they rotate in the direction, by means ot racks 14, mounted inspaced 'and opposed relation to each. other in a casing 15 fined to thevehicle and preferably positioned under the front or driyers seatthereof. el pinion 16 is mounted in said casing between the racks andengages them both, an operating handle 17 connected to the pinionprojecting forwardly of the casino' to within convenient reach or thedriyers hand.

Flexible wires 1S extend from the rear ends ot the racls to the lowervends or" bell cranks 19 pivoted on the brackets 1 below the shafts 3.saidwires being enclosed and guided in tubes 20.

@n the upper ends of the bell cranks are segmental ,gears curvedconcentric with the axes of said bell cranks, which mesh with pinions 22xed on the shafts 3.

rlhe toothed members are so proportioned with relation to each otherthat with a predeterminel are ot throw ot the handle 17, the signals flWill be moved through a complete halt-turn, or from a horizontalposition pointing` to the left, to a similar position pointingt-o theright7 or vice-versa.

The members 2O arranged in opposite relation to each other, so thatbot-h signals Will trrn in the same direction when one rack lll movesback and the other forward, which Will ot Course be the relativemoyenient imparted thereto with the rotation ot the pinion ltS. Y

These racks are set an angle to each other so that the Wires 18 may runin a substantially straight line troni the racks to tlie leiter en ds otlthe men'ibers 20.

From the Aforegoing` description it. will be readily seen tha"l l haveproduced such a device as substantially tultills the objects ot the inteion as set tortli herein.

While this s'peeiiieation sets torth in cetail the present and preferredconstruction ot the derice, still in practice such deviations 'from suchdetail may be resorted to as do nottorm a departure from the spirit of'the invention, as defined by the appended claims.

raving thus described my invention, what l claim as new and useful anddesire to secure by Letters Patent is:

l. A direction signal structure tor vehicles comprising a pair otturnable shafts extending;` longitudinally of the vehicle on oppositesides thereof. signal members mounted on the shafts at right anglesthereto, pinions on the shatts, hell cranks arranged in opposed relationto eaoh other mounted in i'ired relationwith the sha-tts, segmentalgears on one end ot the bell cranks, and means applied to the tree endsot the latter for moving the same simultaneously and in voppositedirections.

2. A direction signal structure ltor vehicles comprising pivoted signalmembers mounted on both sides et the vehicle and arranged Vtortransyerse swingt movement, both signals pointi in the rame direc-tionlaterally of the vehicle, a turnable handle, and means wherebyv With theturning of said handle both signals will be swung simultaneously and inthe same direction.

3. A. direction signal structure `torvehieles comprising a pair ofturnable shafts extending longitudinally of the vehicle on oppositesides thereof, signal members mount.- ed on the shaitts at right anglesthereto, pinions on theV shafts, ley-er members pivoted in fixedrelation with the shafts. segmental gears on the outer ends et' ilmembers meshingwith the pinions, and "tiexible members by means oitwhich said levers may be moved `from a distance simultaneously and inopposite directions conneeter thereto.

fl. A direction signal structure toryehicles comprising' a pair oit'shafts extending; longitudinally of' the -vehicle `and mounted onopposite sides thereof, signal members mounted on the shafts at rightangles thereto7 pinions on the shafts, bell cranks arranged in opposedrelation'to each other mounted in ixed relation with the shafts,segmental gears on one end ot the bell cranks meshing With the pinionsyVtlexible members from the opposite ends ot the cranks7 and means formoyingj said members in opposite directions simultaneously.

5. A direction signal tor vehicles comprising; a support adapted to bemounted on a tender ot' the vehicle, a shatt turnably mounted in thesupport in a plane longitudinally ot the vehicle. a signal membermounted on the shaft at right angles ther to, a pinion on the sha'tt, abell crank pivoted on the support, a segmental gear on one end of thebell crank and meshing with the pinion, and means connected to the otherend ot the bell crank for moving the same.

In testimony whereof I a'rlix my signature.
